(A) The design and improvement standards for intersections are minimums for all street intersections in subdivisions. All such intersections shall be designed and constructed in accordance with the standards as specified in Table 4.
(B) Multiple intersections involving junctions of more than two streets shall be avoided.

Clear sight distance (length along each approach leg) | 90 (ft.) |
Maximum approach speed | 25 (mph) |
Minimum angle of intersection Streets shall remain in the angle of intersection for at least 100 feet beyond the point of intersection. | 75 degrees (90 degrees preferred)* |
Minimum centerline, offset of adjacent intersections # (1) Local-local (2) Local-collector (3) Collector-collector (4) Collector, marginal access-arterial | 150 (ft.) - all cases 200 (ft.) - all cases 300 (ft.) - all cases 1,320 (ft.) - all cases |
Minimum curb radius (1) Local-local (2) Local-collector (3) Collector-collector (4) Collector, marginal access-arterial | 25 (ft.) - all cases 25 (ft.) - all cases 30 (ft.) - all cases 35 (ft.) - all cases |
Vertical alignment with intersection | Flat |
* The angle between centerline shall be 90 degrees whenever possible. # Centerline offsets shall be avoided whenever possible. | |
